Air source heat pumps
Heat pumps in Durham City
Heat Geek trained installers covering Durham City and the surrounding County Durham area. £7,500 BUS grant handled, full room-by-room heat loss survey, MCS certified.
The Heat Geek difference in Durham City
A heat pump is only as good as the system it's installed into. The most common complaints — high running costs, cold homes in winter, noisy units — almost always come from installs where the heat loss wasn't calculated properly, the radiators were undersized for low-temperature operation, or the controls weren't commissioned correctly.
Our installers are Heat Geek trained, which means every Durham City install starts with a proper room-by-room heat loss calculation, designed flow temperatures, emitter compatibility checks, and rigorous commissioning. The result: heat pumps that actually deliver the COP they were sold on.
Durham County Council declared a climate emergency in 2019 and is targeting a net-zero council estate by 2030, alongside a wider county net-zero ambition for 2045. Durham City’s World Heritage Site (cathedral + castle + their setting) creates specific planning constraints in the historic centre.

Local context
Why Durham City matters for heat pumps
The Durham World Heritage Site buffer zone covers a substantial chunk of central Durham — including parts of the peninsula, the Bailey, Saddler Street and Silver Street — and any visible alteration to roofs within it can require both conservation-area consent and a heritage assessment. The good news for solar is that the suburbs ringing the city (Belmont, Bowburn, Framwellgate Moor) sit well outside the buffer zone with no additional restrictions.

The £7,500 BUS grant
How the Boiler Upgrade Scheme works for Durham City homeowners
The Boiler Upgrade Scheme (BUS) is a government grant currently providing £7,500 towards an eligible air source heat pump installation in England and Wales. It's not a cashback — it's a contribution to the installer (us), which we deduct directly from your quote.
Eligibility
Most Durham City homeowners are eligible. The main requirements: the property must have a valid EPC (no outstanding loft or cavity-wall insulation recommendations, or those must be exempted); the property must be currently heated by fossil fuel (gas, oil, LPG, coal) or electric storage heaters; and the heat pump must be designed to replace the existing heating system fully.
The process
We handle the BUS application as part of every Durham City heat pump install. The sequence: free survey → fixed-price quote → BUS application submitted by us → Ofgem voucher issued (usually within 2-4 weeks) → install scheduled → install completed → final paperwork → grant payment received by us → your invoice nets off the £7,500. You never need to interact with Ofgem directly.
Combining with other grants
BUS can be combined with other targeted grants if you qualify — the Home Upgrade Grant and Warm Homes Local Grant administered through your local authority may provide additional support for lower-income households. We can advise on what's currently available for Durham City residents during the survey.
Scheme longevity
BUS is currently funded through to early 2028, with the grant level at £7,500 for air source heat pumps and £7,500 for ground source heat pumps. Government policy can change, but the current programme is well-established and budget remains available.
What's included
What you get for your fixed-price Durham City heat pump quote
- Tier-1 heat pump. We install Mitsubishi Ecodan, Vaillant aroTHERM, and Daikin Altherma — all premium-tier units with proven track records in UK conditions, all rated A++ or higher, all backed by 5-7 year manufacturer warranties.
- Heat Geek trained design. Every Durham City install starts with a proper room-by-room heat loss survey (not a rule-of-thumb sizing). We design flow temperatures, emitter sizing, and control strategy to deliver the COP the unit was sold on — not "fit it and hope."
- Indoor cylinder. A new hot water cylinder sized for your household's actual demand. Most Durham City homes get a 180-250 litre cylinder.
- Pipework, controls and commissioning. All new pipework between heat pump, cylinder, and existing emitters. Weather compensation controls (essential for real-world efficiency). Full commissioning and verification against the designed flow temperature.
- Radiator upgrades if needed. Where our heat loss survey shows existing radiators won't deliver enough heat at the designed flow temperature, replacement radiators are quoted in advance — not as a day-of-install surprise.
- Removal of old system. Decommissioning of the existing boiler / oil tank / LPG plumbing as part of the install, where applicable. Disposal of waste handled.
- £7,500 BUS grant applied. Net pricing after grant — you see the after-grant figure on your quote, not the before-grant figure.
- MCS certification and full paperwork. MCS certificate, building control notification, and ongoing energy performance assessment included.
- 7-year manufacturer warranty + our 5-year workmanship guarantee. Total package covers both the kit and our installation work.
Heat pumps in Durham City
What makes a Durham City home a good heat pump candidate?
Current heating fuel
Most Durham City homes are on the gas grid (around 6% are off-gas). For gas-grid customers, the heat pump payback is longer than for oil/LPG, but still attractive: typical running costs are similar to or slightly below gas, with much lower carbon emissions and the £7,500 BUS grant reducing the install cost.
Property fabric and insulation
Durham City's housing stock has an average EPC of around D, which is typical for the North East. Heat pumps work in EPC D and E homes — we've installed plenty — but performance and running costs are best when the fabric is reasonable. We assess heat loss room-by-room and advise on any fabric upgrades that will materially improve performance.
Radiator compatibility
Heat pumps deliver heat at lower flow temperatures than gas/oil boilers — typically 35-50°C versus 60-80°C. That means existing radiators need to be sized to deliver enough heat at the lower flow. In most Durham City homes, we find 1-3 radiators need upgrading (typically in larger living rooms or older bedrooms where the original radiator was undersized). It's almost never a full system replacement.
External unit location
The outdoor unit needs a position with airflow, ideally rear or side of the property and at least 1m from the boundary to comply with permitted development rules. Most Durham City properties have a workable rear or side location. Terraced properties sometimes need creative siting — we work this out during the free survey.
Running cost expectations
For a typical 3-4 bedroom Durham City home replacing a gas combi, a well-designed heat pump should deliver roughly comparable running costs at current energy prices. Replacing oil or LPG, you should expect annual heating costs to drop by 30-50%. The big efficiency gains come from getting the design right — flow temperature, emitter sizing, weather compensation controls — which is why we use Heat Geek methodology rather than templated installs.
Honest assessment
When a heat pump isn't right for your Durham City home
We won't sell you a heat pump that doesn't fit your home. Here are the cases where we'd recommend you stay with — or replace like-for-like — your existing heating instead:
- You're planning to sell within 3-4 years. Heat pump payback typically takes 7-15 years. If you're selling soon, the heat pump's running-cost savings won't accrue to you, and the resale uplift on a heat-pump-equipped property — while real — is currently modest in most Durham City property markets.
- Your home has severe insulation issues that can't be addressed. Heat pumps work in EPC D and E homes — we install plenty — but if your Durham City property has a heat loss above ~140 W/m² that can't be reduced through insulation, the heat pump capacity needed becomes expensive, the runtime hours go up, and the cost-effectiveness deteriorates. Sometimes the right answer is to invest in fabric first.
- There's no viable outdoor unit location. A rare situation in Durham City but it happens — typically a flat without ground-floor access to outdoor space, or a property where conservation rules block any unit placement. In these cases an air-to-air system or staying with gas may be the practical answer.
- You have a recent, working boiler. If your gas boiler is under 5 years old and operating well, the financial case for replacing it now is weaker. Better to plan a heat pump for when the boiler nears end of life (around year 12-15). We'll happily survey now to give you a future quote.
- Listed-building constraints prevent emitter upgrades. A Grade I or II* listed property in Durham City sometimes can't accept any radiator changes. If our heat-loss survey shows the existing emitters can't deliver enough heat at the heat pump's flow temperature and there's no consent route for upgrading them, we'll be honest about it.
Where any of these apply, we'll tell you directly. We'd rather not have your money than fit a system that disappoints you.
